- Introduction
- ************
-
- This package contains OS/2 Presentation Manager drivers for ATI
- VGA Wonder video adapters, for the 800x600x256c and 1024x768x256c
- resolutions. They have been tested on IBM OS/2 1.3 and OS/2 2.0 (Level
- 307N).
-
- Files in this package:
-
- ati800-8.dll (800x600x256 driver)
- at1024-8.dll (1024x768x256 driver)
- atipat2.exe
- atipat2.c
- readme.txt
-
- Please read this file carefully before trying to install the PM
- drivers. If you don't, OS/2 could become corrupted forcing you to
- reinstall it.
-
- IMPORTANT: I (the author) have absolutely no contact with ATI
- Technologies Inc. I have developed this driver during my spare time,
- and I am distributing it as FREEWARE. However I will greatly
- appreciate any donation, since I have spent a considerable amout of
- time (40000 ASM lines...).

- Installation
- ************
-
- Let's suppose you want to install the 800x600x256c driver. The
- file ATI800-8.DLL is a replacement for the OS/2 file DISPLAY.DLL.
- Since there are lots of ATI Wonder models, a utility is supplied
- to accomodate the PM driver for your card and monitor. This utility,
- ATIPAT2.EXE, will patch the ATI800-8.DLL file. I recommend that you
- patch a copy of ATI800-8.DLL, keeping the original file.
-
- To install the PM driver complete the following steps:
-
- 1) Uncompress the ATIPAT2.EXE and ATI800-8.DLL somewhere on your disk.
-
- 2) Run ATIPAT2.EXE. The first argument is the name of the file to
- patch, namely ATI800-8.DLL:
-
- C:> atipat2 ati800-8.dll
-
- ATIPAT2.EXE is a DOS program! It works fine in the DOS
- compatibility box (OS/2 1.3), or in a FULL SCREEN Dos session of OS/2
- 2.0. It you get a warning message saying that the driver will probably
- not work, you can still try it... If you have a problem with ATIPAT2,
- and if you know what are video registers, I have included the source
- code of ATIPAT2.EXE. If you make any modification to it, please send
- it back to me.
-
- 3) The file DISPLAY.DLL is usually in the \OS2\DLL directory of the
- boot drive. But you CAN'T replace this file while OS/2 is running.
- So boot DOS to replace it. The key point is to always keep a backup
- of this file, in case the ATI driver would not work.
-
- So for instance:
-
- C:>CD \OS2\DLL
- C:\OS2\DLL> REN DISPLAY.DLL DISPLAY.OLD
- C:\OS2\DLL> COPY <patched ati800-8.dll file> DISPLAY.DLL
-
- Note: if you installed OS/2 on an HPFS partition, you will have
- to boot on the installation diskette. When the IBM logo appears, press
- ESCAPE to have access to an OS/2 command prompt. Then you will be able
- to see your HPFS disk, and replace the DISPLAY.DLL file.
-
- 4) Reboot your computer. If the PM screen doesn't show up in 800x600,
- then there might be a problem with your ATI adapter... Replace the
- DISPLAY.DLL file with the old display driver you backed up,
- DISPLAY.OLD. Try to contact me to fix the problem.

-
-
- ***************
- OS/2 2.0 users:
- ***************
-
- OS/2 2.0 users should install SVGA support BEFORE installing the
- PM driver. Type SVGA ON in a full screen DOS session to do so (for
- further information, refer to the OS/2 V2 documentation). Then when
- you type SVGA STATUS (in a full screen dos session), OS/2 should
- report that you have an ATI chipset.
- Warning: a 1024x768 background picture consumes 768Kb of main
- memory! I do not recommend such pictures if you don't have at least
- 8Mb of memory.
-
-
- ******************
- Known limitations:
- ******************
-
- The 256-color drivers do not work on old ATI Wonder adapters
- (chip rev 1, without dual-page mode).
- For the 1024x768x256 resolution, you need 1Mb on your video card.
- These drivers are not real 2.0 drivers: no new icon pointers, no
- palette manager functions, etc. I am still waiting for IBM to provide
- me 2.0 sample source code...
